Abstract: The optical fiber line intelligent monitoring system of regional power grid is taken as the research object, and its data transmission technology is studied. The database technology, computer technology, GIS technology, network communication technology and OTDR test technology are used to study the composition and functions of the optical fiber line intelligent monitoring system, system structure design, OTDR optical fiber intelligent monitoring implementation of the system key module, fault location judgment of GIS optical fiber monitoring, and location of GIS optical fiber fault intelligent monitoring. The system using the optical cable line landmark information stored in database is tested with OTDR to display the landmark information of the fault location directly, provide the accurate and intuitive visual fault information to the maintenance staff, reduce the maintenance cost further, and avoid the loss of system breakdown caused by communication interruption, which provides a reference for the future application of the optical fiber line intelligent monitoring system of regional power grid.

区域电网实质上属于一种区域电力的市场模式,其特点是以区域性的电力系统为基础[1]。保障电力系统生产安全和高效运行的是光纤传输网络[2?5]。随着数据通信量的不断增长,光缆通信是信息传输的主要媒介,其具有越来越重要的作用,但因光纤具有较大的容量,在发生故障时,中断时间较长,会导致无法弥补的损失[6?9]。 要做到电力系统安全稳定,就要在光缆线路的传输性能正常运行到突然出现下降时进行预警[10]。智能在线监测是电力体系光缆线路的发展趋势。
目前,随着智能电网的快速发展与普及,区域电网光缆通信智能检测传输数据技术变得日益重要。……
